WINCH.

Application filed May 28,

a frame attached to the rear of the tractor supporting a winding drum, intended to be driven from the belt pulley shaft of the tractor. In machinery of this type, an economy of space and parts is desirable.

The object of the invention is to simplify and reduce the number of parts to a minimum. Another object of the invention is to provide a more secure mounting of a brake lever and at the same time employ a portion of the lever as an element of a gear shift. Other objects and advantages of the invention will hereinafter appear and the novel features thereof willbe particularly pointed out in the appended claims.

Like letters of reference indicate like parts throughout the several figures of the drawing, in which i Figure 1 is a rear elevation of a portion of a winch or winding drum adapted for attachment to a tractor, y

Figure 2 is a side elevation of certain of the parts, a

Figures 3, 4 and are details taken on the lines 3 -3, 44 and 5-5 of Figure 1. The side frame element has formed integral with it a bearing block 11 in which is mounted a countershaft 12, it being understood that these parts are found at each side of the machine.

Upon the shaft 12 is mounted the pinion 13 which is adapted in. operative position to mesh with the gear 14 forming a part of the winch spool. This pinion is designed to be shifted out of mesh with the gear into the position shown in Figure 1, the pinion being provided with a grooved portion in which a yoke 15 fits.

At the opposite side of the spool is the brake drum 16 held by the brake band 17 which is looped around an eccentric 18, oscillating with the shaft 19. The opposite end of the brake band is adjustably mounted in the frame of the winch as shown at 20.

A shift lever 21 pivotally mounted on the 1928. Serial No. 281,168.

winch frame at 21 and a nipple 21 accomplishes the shifting of the pinion into and out of mesh with the gear.

The parts just described are elements of what is known in the field of Fordson equipment as the Myers winch, on which the present invention is an improvement. Partieularly is the present inventian an improvement on the inventions described and claimed in the patents of Harry S. Myers, identified as follows:

1,413,421 dated April 18, 1922, for hoist brake, and 1,414,038 dated April 25, 1922, for

gear shift, and constituting a combining of the gear shift and hoist brakein a single assembly.

The shaft 19 is mounted in the winch frame in complemental apertures 22 and 23 and extends from one side frame to the other. The lever 24 is employed to rock the shaft and the eccentric 18 to produce a binding of the brake band on the brake drum. The shaft 19 is drilled to receive a pin 24 designed to limit the movement of the shaft in one direction and further drilled to receive a taper pin 25 which will limit the movement of the shaft in the opposite direction; the eccentric 18 is made sufliciently wide to occupy the space between the apertured lug 23 and the, pin 25.

The pivot 21 is provided by the bolt 26 secured to the angle 27 b the nuts 28 and 29. The end of the lever 21 is apertured to receive the bent end of the bolt 26 and is held between washers on said bolt. A drill hole is provided near the bend of the bolt to receive a pin 30 which supports the washers in 1proper position under the head 31 of the Slidably mounted upon the shaft 19 are the yoke 15, the elongated nipple 32 and the T 33. It will be appreciated that the elongated nipple 32 is screwed into the threaded aperture in the yoke 15, and into one end of the T 33, and that these three parts move together under the influence of the shift lever 21 to shift the pinion 13 into and out of mesh with the gear 14. A hole is drilled at 34 in the shaft 19 to receive a cotter or pin which may be employed to prevent shifting of the pinion into mesh with the gear when that is desirable, as when the machine is being transported from place to place.

The connection between the T 33 and the lever 21 is formed by providing an elongated opening 35 in the lever 21, in which a short biiity.

nipple 86 operates, the nipple being screwed into'the opening in the T and'having a cap 37 screwed upon its opposite end.

It will be appreciatedthatbymy construction there is produced a simplified winch construction and that the parts forming the-invention are largely stock material and readily replaceable in case of breakage. 7 From the foregoing description the func- 10 tiono'i? the individual p'arts will be apparent, and it'will alsobe' appreciated thatthe shaft .19 is utilized as the'inain support for both thefbra'lteassembjly and the gearshift assembly.-; Underthemanipulations;of the lever Q1,ztheielongated'nipple 32 andassociate parts a'reslfidable up'on'the shatt'19, and under the i ranipa'iation erthelever 524, the shaft 19 retained within" the nip- 51532. ItwiiPb'e appreciated that the position of 20 the lever 21 is determined by the length of the-nipple32am the limits of traveldefined byftl'iedength of pivotope'ning The;presentinvention is particularly design-ed tor incorporation into the which at- 25 tachment for tractors forming the subject .I iii'atter of acopending application, which when attaehmentis capable of being mountettupon either the rear or the front of a tractor; To"aceompl is'hthis result, portions tethe-wi elr'mast possess a Certain reversibiiity ofposition with respect to each other. The fpr'e's'eii't invention possesses such capa- 'fgitss uniing-"that the; parts of the winch are bereversed,"'the han'dle 24 and eccentric :ISmifustaPp'ear on the'l'eft of Figure'l while I they'olte '1'5"ihustb'e' mi the right of Figure 1, f it being 'understood'that the pinion '13 and gear 14: will have beenshiftetl to the position 40 occupied'b r the'b'rake' drum 1 6, and the drum were position of'the' gearla The-"bolt 26 joceupies a "position centrally of the winch "side frame, "and does not require attention.

"' Aftfer'the side frame '10 "totheleft of i 'Figure'l IlS"Il31llOVd,"i;lIe' spool of the winch -isf 'se'paratfe'd from the side "frame to the right. "The-cap 371's theirre'ni'oved from the pivot 35 and the lever 21 lifted clear of the pivot. In this position of the" parts the pinion may be'slidrefi' tlie cotrnte'rshaft Eat the same timed-hat they he 15, long nipple 32- and T "33 areremoved from the shaft lS).

Next the sprocket isiremovedfrom the end of"the"countershaft l2,- and the shaft 12 removed"fromthvwinch"frame. Thetaper piifi 25'- is-themremove'd from shaft 19, when -and'the' brake band may be removed with the 'eccentrie if its connection -20 with the frame "crossrail is released.

-Theishaft 1-9-isthe'n slid to the right tore move itfrom the ear 23. For this purpose,

" 1 'how'ever,'suitableprovision must bemade tor either removing the eccentric key from the '65 sha'ft or' clearing-it tl-irough" the aperturei in the car. It is preferred toprovide in each oi: the cars 22 and 23 a keyway addition 38 to the shaft: bearing aperture.

iThepartsmay be again assembled in the reverse order of their removal. The shaft is: passed through car 22, the eccentric with band replaced, and the T, long nipple 'and' yolte slid upoir'the shaft 19 at the same time that the pinion is slid upon the countershaft'. "TheVleve'r 21 isa'gai'n connected to the'T 33.

It will=be appreciated that the change of position ofthese parts is accomplishedby a minimum of effort, and with the exception of the sprocket collar set screw, the cap 37, and connection 20, none of the parts is unscrewed.

Havin g' described my invention, what I claim asnew and desire to secureby Letters Patent is oscillation of the shaft, and means carried by the shaft for shifting a drive pinion into and outer mesh with the spool gear.
